Summon Faer Gorta

Summon Faer Gorta is an active ability in the third tier of the Sorcery tree. It unlocks the Summon Faer Gorta ability, which allows you to summon a skeletal warrior that will fight for you for 120 seconds. Note that it takes a few seconds to cast, and that the Faer Gorta isn't the brightest, occasionally opting to wander around rather than actually fight anything. Once it finds an enemy it does fine though. So watch out for that.
